This is the third magnifying mirror I've owned in various houses.  The mirror is well made and YES difficult to install....get a pro to do it!  I'm disappointed that it only has one light setting and it seems dim to me.  I am used to a 10X magnification so the 8x is almost not enough. My eyes are pretty bad though :)  For me, next time I would choose a 10 X,  2-light setting model. 

Pros: good value, sturdy
Cons: low light, not enough magnification for people who need reading glasses.
